A working copy of U-Boot will allow you to flash images. Please refer to the U-Boot Manual located at www.DENX.de.
If the Main Flash U-Boot image is corrupt restore U-Boot from the Backup Flash. Please refer to the ADS512101 Quick Start Guide or Section 7.3 of the ADS512101 Userís Manual.
If both U-Boot and Backup Flash are corrupt, STx can recommend using the Abatron BDI3000 JTAG Debugger for troubleshooting. STx uses this product internally to develop its boards. You can purchase the Abatron BDI3000 (BDI2000 for CodeWarrior) from STx directly.
Please refer to Section 3.2 of the ADS512101 Userís Manual.
Verify that the P4 jumper for backup flash is removed. If you re-installed u-boot the MAC address may have to entered. See instructions to locate and reinstall the MAC address in either the Quick Start Guide or User Manual.
STx has added several patches for LTIB. Freescale will release a new revision late in May 08 with these and other patches included. See our download site for LTIB Changes.
